Tutorials

In the context of the symposium, tutorials on the following selected topics will be simultaneously provided on September 26, 2012. The tutorials will start at 09:30 a.m., registration starts at 09:00.

Fees for the tutorials: Participants/Authors/Students EUR 200,- (Early bird price: 150,-).

The registration for the tutorials is independent of the symposium registration. For more details please see the registration site.

Evaluation of urban transportation investments

In the first part of the tutorial, the theoretical background and methods for evaluating urban transportation investments will be presented.

These include financing formalities in Germany, goals and procedure of the “Standardised Evaluation of Investments on Public Transport”, determination of traffic supply and demand for public transport and private transport, evaluation of costs and benefits, determination of macroeconomic indicators and calculation of subsequent costs.

In the second part the participants will have the opportunity to evaluate a concrete example by using a software tool.

Innovative approaches to railway capacity analysis

The main aim of railway capacity research is the improvement or optimization of the current, future, or recommended operational railway situation. This can be achieved in a number of different ways, one of them being through the analysis of the number of trains and their corresponding average waiting times, and then determining the optimal area of traffic flow. Improving railway operations can lead to decreased passenger and freight delays, increased profits for railway companies, and improved passenger comfort.

This tutorial consists of two parts:

In the first part of the tutorial, an introduction to capacity research will be given and several different research and evaluation methods of capacity analysis will be presented. The topics of asynchronous and synchronous simulation techniques, including their pros and cons and implementation areas will be then focused on in more detail.

In the second part of the tutorial, the software tool, PULEIV, developed by the Institute of Transportation Research at the University of Stuttgart will be introduced. PULEIV is designed based on the analytical evaluation method according to Hertel, but executed via its interface with the synchronous railway simulation software “RailSys”. This new software tool greatly reduces the amount of work needed to carry out Hertel’s method by automating many of the tedious steps that were previously conducted by hand. The second part of the tutorial will also include a hands-on exercise in PULEIV.

Positioning and map matching for traffic application

This tutorial will focus on various positioning techniques in combination with digital maps. It consists of three parts. There will be no practical training but practice-oriented talks presented to the participants.

A) GNSS and Multi Sensor Systems

The first part will focus on sensors applicable to car navigation systems. GPS respectively GNSS is one well-known satellite-based positioning system.Due to the fact that these satellite based methods show a reduced availability and correctness in urban areas, additional sensors like odometers, accelerometers, gyroscopes or a speed signal have to be integrated. This leads to multi-senor systems that are well suited for navigation purpose.

B) Digital Maps and Map-Matching

A possibility to strengthen positioning results for navigation purpose is the use of digital map data: the process to reference the trajectory on the digital map is called map-matching. First the base regarding navigable digital maps has to be explained. In the following the matching process isdescribed: the measured trajectory of the vehicle is compared with possible routes in a digital database of the road network leading to the extraction of the most suitable route by coordinate and shape comparison.

C) Mobile Phone Positioning

The last part of the tutorial will focus on mobile phone positioning including map-aiding methods applied to traffic state acquisition. Different mobile phone positioning methods will be compared and a network-based approach is explained more in detail. Signal-strength matching methods are combined with a Kalman-filter based approach and a subsequent map-aiding using planning data of the mobile phone provider.
